Question

lim x tends4 (x^2-7x+12)÷(x-4)​

Answer 1

Step-by-step explanation:

lim x > 4 (x² - 7x + 12)/ (x - 4)

=> lim x > 4 ( x² - 4x - 3x + 12)/(x - 4)

=> lim x > 4 [ x(x - 4) - 3( x - 4) ] / ( x - 4)

=> lim x > 4 [(x - 3)(x - 4)]/(x - 4)

=> lim x > 4 ( x - 3) [ x - 4 cancel in numerator and denominator ]

=> 4 - 3 => 1 Answer
